4th Gen RGB Tandem OLED: The Brightest UltraGear™ Monitor

Equipped with the latest generation 4th Gen Primary RGB Tandem OLED panel, the 27GX790B-B achieves a typical brightness of 335 nits, the highest ever in an UltraGear OLED monitor. The advanced 4-layer RGB structure offers enhanced contrast, color accuracy, and excellent visibility even in bright rooms, while consuming less energy.

Lightning-fast 0.02ms Response Time and DisplayPort 2.1

With a response time of just 0.02ms (GtG), reverse ghosting is eliminated, offering perfectly clear images during every sudden movement. The integration of DisplayPort 2.1 provides the massive bandwidth required for stable gaming at high refresh rates, while the two HDMI 2.1 ports and the USB-C port ensure full connectivity with PCs and next-generation consoles.

DisplayHDR™ True Black 500 and Absolute Black

The VESA DisplayHDR™ True Black 500 certification and the 1.5M:1 contrast ratio guarantee absolute blacks and stunning detail in dark scenes. With a 99.5% DCI-P3 color gamut and Delta E≤2 accuracy, the monitor delivers colors exactly as intended by the creators, offering an immersive experience that is also UL-verified for its color fidelity.

ClearMR 21000 Certification for Elite Motion Clarity
